BED.

SPECIFICATION forming part of Letters Patent No. 596,166, dated December28, 1897'.

Application filed May 19, 1897.

To all whom it may concern:

Be it known that I, JOHN KASCHENBACH, of Wilkes-Barre, in the county ofLuzerne and State of Pennsylvania, have invented certain new and usefulImprovements in Beds; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in beds, and more particularly tocouplings for metal bedsteads, the object of the invention being to soconstruct a coupling between the rails and posts of a bedstead that awide or extended bearing of one part relatively to the other can be had,whereby to insure the rigidity of the bedstead and avoid all possibilityof the shaking of the same when in use, as well as danger of thecoupling becoming loose.

A further object is to produce a coupling for metal beds which shall besimple in construction, comparatively cheap to manufacture,-and whichshall be effectual in all respects in the performance of its functions.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claim. I

In the accompanying drawings, Figure 1 is a View illustrating myinvention with the parts of the coupling sep'arated. Fig. 2 is a View ofthe coupling with the parts united. Fig. 3 is a sectional view. Fig.4 isan end View.

A represents the post of a metal bedstead, and B one of the rails.

The post A is provided at a suitable point between its ends with anelongated enlargement 1, having its diametrically opposite facesflattened, as at 2, so as to form inclined shoulders 3, disposedpractically at diametrically opposite sides of the enlargement 1.

The rail B is provided at its end with a yoke 4, which is preferablymade semicircular, so as to conform to the curvature of the face 5 ofthe enlargement 1 and lie closely against the same, thus forming a longbearing between Serial No. 637,247. (No model.)

the rail and the post. The free ends of the arms of the yoke 4 are madeinternally with inclined shoulders 6, which when. said yoke is slid ontothe enlargement 1 will engage the shoulders 3 thereon. The shoulders 3and 6 being inclined, it is apparent that as the yoke is forced down itwill be made to embrace the enlargement 1 and its internal face will bedrawn tightly against the curved face 5 of said enlargement.

Owing to the wide bearing between the rail and the post afforded by myimproved coupling, the bedstead will be made rigid and not liable toshake or become loose. My improved coupling also affords quick and easymeans for connecting the parts of the bedstead in a tight and efficientmanner.

My improvements are simple in construction, comparatively cheap tomanufacture, and are effectual in every respect in the performance oftheir functions.

Slight changes might be made in the details of construction of myinvention without departing from the spirit thereof or limiting itsscope, and hence I do not wish to limit myself to the precise detailsherein set forth.

I-Iaving fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

The combination with a post having a curved or cylindrical portionthereon, said curved or cylindrical portion flattened at opposite pointsand provided with inclined shoulders adjacent to these flattenedportions, of a yoke adapted to span this curved or cylindrical portionand provided with inclined shoulders which embrace the shoulders on thepost whereby as weight is applied the bed is drawn tighter and tightertogether.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JOHN KASCHENBACH.
